QuickStats: Percentage of Adults Aged ≥65 Years Who Have Lost All Their Natural Teeth,* by Poverty Status† --- National Health Interview Survey, United States, 1998--2009§

* Based on response to the question, "Have you lost all of your upper and lower natural (permanent) teeth?" In 1998, separate questions were asked about upper and lower tooth loss.

† Poverty status is based on family income and family size using the U.S. Census Bureau poverty thresholds. Family income was imputed when information was missing, using multiple imputation methodology.

§ Estimates are age adjusted using the projected 2000 U.S. population as the standard population and three age groups: 65--74 years, 75--84 years, and ≥85 years. Estimates are based on household interviews of a sample of the civilian, noninstitutionalized U.S. adult population and are presented as 3-year annual averages to increase reliability.

During 1998--2009, the percentage of older adults who had no natural teeth was higher among those in families with low income than in families with higher income. Among all income groups, the prevalence of no natural teeth was lower during 2007--2009 (25.3%) than during 1998--2000 (31.0%).
